I recently purchased a cabin. This cabin has no electricity but has a 12v and 110v lights system inside. I recently decided to add a 12volt solar system, I purchased 4-6v 200ah AGM batteries, a 2000 watt inverter, a 250 watt panel and a 30amp mppt controller. I messed up and should of bought a 40amp controller because so I could add another solar panel. My question is can I switch my system to a 24v system ?? This would allow me to buy another panel without purchasing another controller, also I am told my inverter may do both 12v and 24, is that possible ??? And would I have to change my 12v builds to 24v Bulbs??

Never heard of an inverter that could be both 12V or 24V.
Most charge controllers are versatile enough to go 12, 24 & 48V
But before you go any further, what are the Vmp and Voc specs off the sticker on the back of the PV panel, to recharge 24V battery with MPPT controller, you need at least 35V Vmp , 45 would be betterPowerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||
